Solar panel efficiency to increase 50% with first production of ‘miracle’ tandem cells

World’s first commercialisation of perovskite solar cells follows years of breakthroughs with the material

18 hours ago

A South Korean firm has announced the world’s first production line for perovskite-silicon tandem solar cells, which promise an increase in efficiency of between 50-75 per cent compared to standard solar panels.

The commercialisation of solar cells that use perovskite follows years of breakthroughs with the mineral, which has been hailed as a ‘miracle material’ for its potential to transform various industries, including renewable energy.

Seoul-based Qcells said it will invest $100 million to roll out the next-generation solar cell technoloy, which until now has been limited to lab tests and academic research.

The investment will fund a pilot production line at a factory in Jincheon, which is projected to be operational by late next year.

“This investment in Jincheon will mark an important step in securing technological leadership,” said Qcells CEO Justin Lee.

Researchers achieve record 19.31% efficiency with organic solar cells
https://techxplore.com/news/2023-05-eff ... cells.html
by Hong Kong Polytechnic University
Researchers from The Hong Kong Polytechnic University (PolyU) have achieved a breakthrough power-conversion efficiency (PCE) of 19.31% with organic solar cells (OSCs), also known as polymer solar cells. This remarkable binary OSC efficiency will help enhance applications of these advanced solar energy devices.

The PCE, a measure of the power generated from a given solar irradiation, is considered a significant benchmark for the performance of photovoltaics (PVs), or solar panels, in power generation. The improved efficiency of more than 19% that was achieved by the PolyU researchers constitutes a record for binary OSCs, which have one donor and one acceptor in the photo-active layer.

Led by Prof. Li Gang, Chair Professor of Energy Conversion Technology and Sir Sze-Yen Chung Endowed Professor in Renewable Energy at PolyU, the research team invented a novel OSC morphology-regulating technique by using 1,3,5-trichlorobenzene as a crystallization regulator. This new technique boosts OSC efficiency and stability.

The US solar market is projected to triple in size by 2028

Jun 7 2023 - 9:01 pm PT

Due in part to strong Q1 2023 numbers and a surge in demand, the US solar market is now expected to triple in size over the next five years, according to a new report.

According to the “US Solar Market Insight Q2 2023 report,” released today by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, the solar market is now expected to achieve a total installed solar capacity of 378 gigawatts (GW) by 2028.

The US solar industry installed 6.1 GW of solar capacity and had its best first quarter in history in Q1 2023, due to the easing of supply chain challenges and delayed solar projects moving forward.

The Biden administration’s Inflation Reduction Act has also spurred a surge of new manufacturing announcements, with US module capacity expected to rise from fewer than 9 GW today to more than 60 GW by 2026. At least 16 GW of solar module factories are under construction as of the end of Q1 2023.

Despite customer hesitancy, the residential segment installed 1.6 GW of solar capacity in Q1 2023, a 30% increase from Q1 2022.

The largest floating solar farm in North America is officially online

Michelle Lewis
Jun 7 2023

New Jersey is host to an 8.9 megawatt (MW) floating solar farm – the largest floating solar array in North America.

NJR Clean Energy Ventures owns and operates the floating solar farm, which covers 17 acres of the Canoe Brook reservoir in Short Hills, New Jersey. NJR CEV and New Jersey American Water held a ribbon-cutting ceremony for the project yesterday.

The floating solar farm consists of 16,510 solar panels, and the clean power they generate is enough to power 1,400 homes annually. It will provide around 95% of the power needs for New Jersey American Water’s Canoe Brook Water Treatment Plant.

Floating solar consists of PV panels attached to rafts. The water keeps the solar panels cool, thus increasing efficiency, and the panels also reduce evaporation to nearly zero.

Robert Pohlman, vice president of NJR Clean Energy Ventures, said, “Floating solar technology creates new opportunities for underutilized bodies of water, allowing space that would otherwise sit vacant to enable large-scale renewable energy generation, which helps to bring the benefits of clean energy to even more customers.”
